The Mexican rice borer was introduced in 1980 from Mexico into the Lower Rio Grande Valley of Texas, where it soon became a serious pest of sugarcane. In 1987, the Mexican rice borer was detected in Jackson and Victoria counties of the Texas Rice Belt. In 2000, LSU AgCenter and Texas A&M scientists cooperated in setting out pheromone traps to determine the Mexican rice borer spread since 1987.

Formosan termites pose a growing threat to all structural wood materials in residential construction. New products must be developed that are resistant to these aggressive and voracious insects.

The ability of farmers to burn sugarcane is a significant economic factor for the state’s sugarcane industry. Burning of sugarcane before harvest eliminates from 30 percent to 50 percent of the leafy trash (residue), which constitutes from 20 percent to 25 percent of the total weight of the plant.

Integrated pest management (IPM) has two distinctive components—economic protection from pest damage and a more favorable environmental outcome than would occur in the absence of IPM. Integrated pest management is a dynamic process and involves balance among biological, cultural and chemical measures deemed most appropriate to a particular situation after careful study of all factors involved.

Soil fertility and plant nutrition research are important components of the LSU AgCenter’s sugarcane research efforts. With tight economic conditions and increasing concern for the environment, it is important that the nutritional needs of sugarcane be met without applying excess nutrients. To meet this challenge, the LSU AgCenter maintains a rigorous program for examining the nutritional needs of the recommended sugarcane varieties on the major soil groups where sugarcane is grown.

This is a special issue of Louisiana Agriculture devoted to milestones in research over the past 125 years. In 1887, Congress passed the Hatch Act, which provided federal funds to states with agricultural research stations. Lousiana was able to access this money and begin conducting research that made the agricultural industry sustainable and profitables. 32 pages.

Few crops have the storied history of cotton. Grown in Louisiana for hundreds of years, this crop has been a vital part of the state’s economy. In the early 1700s, cotton cultivated in the state was used mainly for home spinning and weaving. It wasn’t until the invention of the cotton gin later that century that cotton became a cash crop in Louisiana.

Rice farming on a widespread commercial basis in Louisiana began in the late 19th century, and rice research soon followed.

Agriculture in Louisiana is an intricate tapestry whose richness is rivaled by few other states. Our broad array of agricultural enterprises ranges from the traditional to the regionally unique – from soybeans and corn to rice and sugarcane, from beef and dairy to alligators and turtles, and from catfish to crawfish and oysters.

Interest in daylilies is still strong despite rust problems over the past several years. New daylily selections and All-American daylily winners need to be evaluated in the Gulf South for landscape performance.

Louisiana agriculture research began with the establishment of the Sugar Experiment Station in 1885, two years before the passage of the Hatch Act.

Louisiana has not always had the plantations of southern pines. This isespecially true for the hills of north central Louisiana.

Efforts in 2003 and 2004 included evaluation of cannas, coleus, angelonias, purslane, lantanas, perennial verbena, annual and perennial salvia, vinca, zinnias, melampodium, petunias, rudbeckia, phlox, daylilies, dianthus, ornamental kale, ornamental cabbage, calendula, violas, pansies, ornamental sweet potatoes, garden mums, African and French marigolds and others.

Traditional pot-in-pot production in a nursery attempts to combine field and container-growing techniques and offers advantages over both production systems.

Rice diseases pose a major threat to rice production. The two major diseases, sheath blight and blast, cause significant yield and quality reductions that cost rice farmers millions of dollars each year. Disease resistance is the best control method, but often it is not available or breaks down after varietal release.

Fusarium wilt and the root-knot nematode are both serious diseases of cotton that cause substantial losses across the Cotton Belt. Both pathogens are common in most cotton-producing areas and often inhabit the same fields. These two pathogens often infect cotton simultaneously, forming a complex that increases the incidence and severity of Fusarium wilt.

In Louisiana, southern green stink bugs and brown stink bugs have become common pests of corn, cotton, grain sorghum, soybean and wheat. In corn, an infestation can cause injury to the plant from seedling emergence through ear formation and grain development. Seedlings punctured by stink bugs exhibit small holes surrounded by localized dead tissue.

Saltwater intrusion into rice production has been a cause for concern in southwest Louisiana for decades. But storm surges from recent hurricanes coupled with recent droughts have brought this problem to the forefront.

Water is an essential resource for aquaculture. No single factor influences the success of aquaculture operations more than the availability of good-quality water.

The LSU AgCenter conducts extension programs to inform Louisiana citizens about water resources and ecosystem policy, protection and conservation.

Most agricultural producers who irrigate are using older diesel power units and old wells where upgrading to newer wells and diesel engines or electric motors needs to be technically and economically evaluated.

Runoff from highway rights-of-way can be difficult to manage. Following extended rainfall duration and short periods of high intensity rainfall water, seepage on sloping soils commences and becomes the dominant mechanism that initiates runoff and erosion.

Aquaculture is a nearly half-billion dollar per year industry in Louisiana. Many aquaculture systems include water filtration to protect fish and maintain water quality, enhancing productivity and the environment.

With an annual statewide-average rainfall of approximately 60 inches per year, only Hawaii receives more rain on an average statewide basis. Louisiana’s proximity to the Gulf of Mexico is the primary source for the state’s rains and makes her just slightly wetter than her central Gulf Coast sisters, Mississippi and Alabama – and notably wetter than Florida

The quality of water resources is a major concern in Louisiana and nationally. Surface and subsurface water quality depends in large part on human activities in the surrounding areas.

In addition to being the showplace for home building ideas, the LSU AgCenter’s LaHouse in Baton Rouge also serves as a model for a sustainable home landscape.

Population growth and urbanization over the last century have raised concerns about stormwater runoff and the environmental impact of the pollutants it may carry, such as fertilizer from home lawns and recreational turf areas.

Managing and restoring coastal wetlands requires knowledge of wetland conditions and the factors creating the desired conditions. Flooding stress, nutrient starvation and salinity stress are the most likely suspects in wetlands that have higher loss rates or appear less productive than typical wetlands.

Tidal surges from hurricanes Katrina, Rita, Gustav and Ike deposited enormous amounts of salt in the sugarcane fields of coastal Louisiana in a period of active tropical weather from 2005 to 2008.

About 40 percent of the nation’s coastal wetlands are in Louisiana and include contiguous freshwater wetlands, contiguous brackish wetlands, and low and high salt marshes. These natural ecosystems are highly productive and serve as critical nursery areas for Gulf of Mexico sea life, ensuring a thriving marine and fisheries industry.

The mantra of the environmental movement reads – Reuse, Reduce, Recycle. In this regard, the ancient farming practice of land application of animal waste is an environmental trifecta – excreta is reused as a fertilizer, thereby reducing the application of inorganic fertilizer while recycling organic matter back into the soil.

The Mississippi-Atchafalaya River carries a large quantity of nutrients, making Louisiana’s estuarine and coastal waters highly productive for commercial fisheries.

Trying to keep the University Lakes in Baton Rouge clean and healthy is a goal of LSU AgCenter researcher Yi Jun Xu, associate professor in the School of Renewable Natural Resources.

Flooding from Hurricane Katrina has resulted in federal and state mandates to raise levees in New Orleans and surrounding parishes.

As the largest bottomland hardwood swamp ecosystem in the United States, the Atchafalaya River Basin offers a tremendous diversity of terrestrial and aquatic habitats that support many economically and recreationally important activities including oil and gas extraction, shipping, farming, timber harvesting, hunting, and commercial and recreational fishing.

Dissolved oxygen (DO) is an important indicator for water quality in surface water bodies. Like most terrestrial organisms, fish and many other aquatic organisms are adapted to a narrow range of DO concentrations.

Water quality describes the chemical, physical and biological properties of water. It embodies many complex characteristics including temperature, dissolved oxygen and other gases

Louisiana grain sorghum fields are threatened by a group on insects that includes the corn earworm, fall armyworm and sorghum webworm.

Wheat is a versatile crop that easily fits into several cropping systems. Additionally, harvest and marketing in the late spring provide producers much needed cash flow to support summer farming activities.

Weed management in wheat is usually relatively simple compared to other agronomic crops, but it does require planning. The most important aspect of managing weeds in wheat is establishing a good stand before weeds emerge.

Since 1999, stripe rust has emerged as the predominant disease of wheat in Louisiana. Losses from stripe rust escalated from zero in 1999 to 5 percent in 2005. LSU AgCenter scientists are focusing on ways to control this disease.

Over the past 20 years, the feed grain industry in Louisiana has generated an average farm gate value of roughly $136 million per year.

Historically in Louisiana, producers will double-crop 95 percent of all wheat acreage with soybeans, so proper management of wheat stubble is critical in maximizing soybean yields.

Choosing varieties for production is among the most important decisions farmers make each season. For maximum profit, producers must select adapted varieties that will perform well in their farm environments.

Aflatoxin is perhaps the major production concern for Louisiana corn growers. LSU AgCenter researchers are taking three approaches to help control aflatoxin.

LSU AgCenter researchers have found resistance in corn borers to commercial Bt corn. The resistance detected in the sugarcane borer is the first major resistance to Bt corn in any corn borer species.

Most producers recognize the importance of managing weeds in corn and grain sorghum and do an excellent job with the tools available. The main weakness in many weed management programs is the lack of early season weed control, which can be critical to maximizing yield.

The sugarcane beetle is a sporadic pest of several crops including field corn, sugarcane and sweet potatoes across many southern states. Only the adult stage of these beetles is reported to cause crop injury.

On-farm demonstrations are nothing new to the LSU AgCenter, and in 2002, a variety/hybrid-based program specifically focusing on soybean, corn and grain sorghum was initiated.

Zinc deficiencies in corn appear to be increasing with sometimes severe effects on yield. The increase may be due to declining soil organic matter, where a little decrease can significantly affect micro-nutrient availability.

The mid-March to early April planting dates required for optimal corn production in Louisiana often result in exposure of seedlings to lower than optimal soil temperatures.

When Hurricane Katrina hit the GulfCoast on August 29, 2005, it disrupted grain transportation on the Mississippi River. More than half the grain exported from the United States passes through the Mississippi River Gulf Grain Transportation and Handling Complex.

Some winter vegetation is easy to control, such as annual bluegrass and common chickweed, while others are difficult, including curly dock and ryegrass.

The recent outbreak of foodborne illness traced to fresh spinach should serve as a reminder for taking food safety measures every day, according toLSU AgCenter nutritionist Beth Reames.

To help continue the supply of new small-grain varieties in the South, a regional cooperative was established among five universities in 2005. Called SUNGRAINS (Southeastern UNiversity GRAINS), the cooperative’s mission is to more efficiently develop wheat, oat, rye and barley varieties for growers and seed producers.

The LSU AgCenter small-grain breeding program was initiated in 1985 when research priorities shifted from variety testing and production practices to genetics and variety development.

Plant breeding is a long-term investment in agriculture’s future. The science of plant breeding has evolved considerably in the past 20 years with the development of techniques such as marker assisted selection and genetic transformation. Yet, even with these improvements,plant breeding is dependent on developing large numbers of breeding lines and testing those breeding lines across multiple environments.

The feed grains are a diverse group of crops, each with a unique set of problems, challenges and opportunities. Feed grains in Louisiana include corn, grain sorghum (milo), wheat and oats.

Several new food products or ingredients have been identified as contributing to human health. Including such ingredients in manufactured dairy products would improve their health-giving benefits. LSU AgCenter researchers are testing how the incorporation of these health-beneficial ingredients in dairy products affects physico-chemical and sensory characteristics.

The introduction of glyphosate-resistant transgenic (Roundup Ready) technology has offered an alternative for control of troublesome weeds in cotton, soybean and corn. One drawback to this technology is that “volunteer” Roundup Ready crop plants originating from seed produced the previous crop year have become “weeds.”

Before the availability of transgenic technology in cotton, weed management programs consisted of herbicide applications to the soil at planting followed by multiple herbicide applications directed underneath the crop in combination with tillage to control emerged weeds. Today, weeds are managed with over-the-top applications.

The projected Louisiana gross farm value of forest products decreased in 2003. The 2003 total sawlog harvest fell by more than 111 million board feet (9.5%) to a cut of 1,116,383,390 board feet.

Tenderness is a major determinant of our enjoyment in eating beef and is based on two factors, said Kenneth McMillin, professor of meat science in the Department of Animal Sciences. Connective tissue, which changes with an animal’s age and type of muscle, is a primary factor, while physical attributes, including the length of the muscle fibers and their relative density also affect tenderness.

Herbicide resistance is defined by the Weed Science Society of America as the “inherited ability of a weed biotype to survive and reproduce despite exposure to a dose of herbicide that was previously effective on the population.”

For more than 10 years, rice producers in southwestern Louisiana have occasionally encountered a mysterious disorder in their crops. LSU AgCenter researchers have methodically worked to unravel the "mystery" and help farmers deal with this problem.

With weeds being a major pest in production agriculture, most growers have come to rely on herbicides to prevent negative effects on yield. Producers may choose from many herbicides, depending on the crop they are growing and the weed species affecting the crop.

Since the release of the first generationof Roundup Ready cotton in 1995, U.S. cotton producers have shown a willingness to adopt this new technology.

Roundup Ready cropping systems, which feature plant varieties genetically enhanced to withstand application of glyphosate herbicide with minimal to no adverse effect on the crop, have proven to be effective and cost-efficient for managing weeds in cotton and soybean.

The Hammond Research Station, just outside Hammond, La., has been undergoing a transformation to provide more research and education for the green service industry.

On April 25, 2006, the LSU AgCenter released two new sugarcane varieties, L 99-226 and L 99-233, in cooperation with the U.S. Department of Agriculture’s Agriculture Research Service Sugarcane Research Laboratory in Houma and the American Sugar Cane League.

Nearly 200 farmers and other agricultural industry representatives attended the annual field day at the Northeast Research Station in St. Joseph, La., on June 14, 2006. The half-day program featured stops at 10 field locations where LSU AgCenter scientists explained their research with row crops.

Perennial weeds such as alligatorweed and redvine are becoming more difficult to control as producers adopt conservation tillage practices.

Because soybeans are planted earlier in Louisiana, different insect species are becoming problematic. One of most concern is the red-banded stink bug.

Bacteria pustule disease

In the summer of 2000, daylily rust was reported for the first time in the United States. It has since spread across most of the country and continues to present problems for home gardeners, commercial landscapers and daylily growers.

As a way to bring awareness to Louisiana’s vanishing coast, the Department of Horticulture in cooperation with the Louisiana Sea Grant College developed an educational program called “Coastal Roots” aimed at elementary and secondary students.

Mosquitoes don’t need blood to live. Their main energy source is nectar from plants.

The spring 2011 issue of Louisiana Agriculture features the soybean, a crop vital to the state's economy. Topics covered include the latest research on how to grow soybeans successfully in the state. Other articles talk about extracts from soybeans and their uses in boosting the nutritional value of foods. Vol. 54 No.2, 40 pages.

In recent years, soybean growers have experienced significant problems with mature plants retaining green leaves, green stems and green pods in soybean fields. The occurrence of these symptoms either alone or together has been termed the “green plant malady,” which is also known as the “green bean” or “green plant” problem.

These nine photos help illustrate the problems with green plant malady.

The tropical and subtropical climate in Louisiana creates conditions that support mosquitoes year-round. Mosquitoes are not only a nuisance but, more important, can transmit several diseases to people and domestic animals when biting for a blood meal. Louisiana is historically host to several viral mosquito-borne diseases such as St. Louis encephalitis, eastern equine encephalitis and LaCrosse-California encephalitis.

Katrina and Rita – names that will live forever – remain a part of the South Louisiana dialog and a pair of storms that will undoubtedly reshape the way Louisiana residents think about tropicalweather. Virtually every aspect of community and business life across the Bayou State continues to display a direct effect from these catastrophes, and their signatures of destruction remain plainly evident in the agriculture and forestry sectors as well.

Despite its relatively small size compared to many other states, Louisiana produces a wide and diverse array of agricultural products. Agriculture is big business and a major contributor to the state and many local economies. Sales of agricultural products provide income to thousands of farm families across the state.

What is leadership? For many people, it is a difficult concept to understand because it is intangible. Even if most people would find it difficult to define leadership, they are likely to know a good leader when they see one.

Soybean producers annually face diseases, insects and environmental stresses that affect the yield and quality of their crop. The use of varieties with resistance to specific pests and stresses is generally considered the most cost-effective solution to these problems.

Soybean viruses have been shown to cause significant yield losses throughout the soybean-producing areas of the world. In the United States, many different viruses infect soybeans.

The double-cropping of soybeans and wheat has become an increasingly attractive option economically for Louisiana farmers because of technological improvements, and about 85 percent of Louisiana wheat acres are doublecropping with soybeans.

Epidemiological observations have consistently shown that incidences and mortality rates of cancers, diabetes, multiple sclerosis, Alzheimer’s disease and several chronic degenerative diseases vary significantly across regions of the world.

Every crop can be damaged by many different diseases and pests throughout its life cycle. In common practice, growers apply pesticides to control different pathogens and insect pests and protect a crop from all possible diseases and pests.

The Louisiana Soybean Research Verification Program allows producers a chance to participate in a program that demonstrates profitability through improved agronomic and cultural practices.In Louisiana, according to the National Agricultural Statistics Service, soybean producers averaged 41 bushels per acre on 1,020,000 acres in 2010.

Sensory tests of a mayonnaise-like product made from soy protein and rice bran oil got high marks from a consumer study in which people were asked to taste and evaluate the product developed by LSU AgCenter researchers.

The most yield-limiting and economically important soybean pest across the southern United States is a complex of stink bugs. Historically, the most common species in this complex had been the green stink bug, southern green stink bug and the brown stink bug.

Louisiana soybean growers have historically tried to protect their crop from a diverse insect pest complex consisting primarily of stink bugs, Lepidopteran defoliators (green cloverworm, soybean looper and velvetbean caterpillar), threecornered alfalfa hopper, and bean leaf beetle. Annually, at least one of these pests causes significant problems and isresponsible for limiting soybean productionby reducing yield.

Raising plants in containers creates unique problems for nursery growers. A series of tests were undertaken to help assess the benefits of different growing techniques.

Weeds compete with nursery crops for water, nutrients and light and can potentially harbor insects and diseases. They are common in all container nurseries and can cause significant losses in product quality and quantity.

Baseline data is needed to help forest and agricultural producers determine their role in the rapidly growing biofuel and energy sector, including small and medium-sized producers.

Topics include personal digital assistants as research tools, nematode-tolerant cotton and endowed professors.

(Vol. 53, No. 2) The focus of this issue is on LSU AgCenter efforts to assure that animal waste is converted into safe uses to grow food and protect the environment.

The productivity and composition of wetland forests depend strongly on hydrological conditions. Minor changes in the frequency, duration and seasonality of flooding can favor establishment and growth of entirely separate groups of species.

Regional increases in flooding are likely to reduce the productivity of baldcypress-water tupelo swamps in coastal Louisiana. Although these trees are merchantable for lumber production, it will be important to design appropriate management plans for these sites.

Water quality monitoring efforts in Louisiana’s streams focus on the concentrations of sediment, nutrients and other compounds in the water. However, activities within the watersheds of these streams actually play the most critical role in determining stream water quality.

Louisiana farmers and foresters could find a silver lining in the cloud of rising fuel prices with the development of new fuels from crops they already grow or could grow.

LSU AgCenter scientists have been researching remote sensing work with airborne lasers to develop three-dimensional pictures to measure the stand and take inventory of a forest.

LSU AgCenter area forestry agent Barry Crain helps youth develop forestry skills during a special 3-hour training event every year before the state 4-H University competition held on the LSU campus in June.

Louisiana is blessed with an abundance of forests and waterways. Miles of rivers, bayous and lakes provide Louisiana’s citizens with fishing, hunting, boating and recreational opportunities, which contribute to the state’s wealth and economic growth.

Since the late 19th century, the global average temperature of the Earth has increased by 0.7 to 1.4 degrees Fahrenheit. The significant global warming has been attributed to human activities such as fossil fuel combustion and land use change, which lead to the increase of the concentrations of greenhouse gases, especially carbon dioxide.

Forests of Louisiana managed for timber production constitute the state’s top agricultural crop, contributing an estimated $4.554 billion to Louisiana’s economy in 2005. Louisiana’s managed forests, which are often loblolly pine plantations, are among the world’s most productive forests at producing timber and fiber.

(Vol. 46, No. 4) This is a focus issue about biotechnology.

In the past decade there have been major advances in molecular genetics research. A wide variety of DNA-based markers have been developed. These include random amplified polymorphic DNAs (RAPD), amplified fragment polymorphisms (AFLP) and DNA microsatellites. These markers are used to map genes, study population genetics and produce DNA fingerprints.

Because of the persistent infestation of the Formosan subterranean termite that has threatened to destroy historical buildings in the French Quarter of New Orleans, a federally funded program called Operation Full Stop was initiated in 1998 to apply areawide treatments to suppress the termite and limit further damage.

About three quarters of Louisiana rice is grown in the southwestern region of the state. In recent years, ratooning (a second harvest from the same planting) has become a common practice for many rice growers in this region. Ratooning allows Louisiana growers to compete with rice growers in other states where the environment is more favorable for rice growing.

Adequate and timely fertilization is an important component of small grain cropping systems. Much research has been conducted on nitrogen, phosphorus and potassium; however, less information is available on the need for the nutrient sulfur.

The United States produces about 10 million tons of rice annually, with about 1.4 million tons in Louisiana. Rice straw can be made into valuable panel products for construction with characteristics superior to wood. Manufacture of rice straw panel products would also be good for the environment, making valuable use of a waste product.

Wood is a renewable natural resource typically preservative-treated to ensure structural integrity in many exterior applications. LSU AgCenter researchers studied attitudes toward treated wood, including surveying a national sample of homebuilders.

Plastic mulch has been used in the production of warm-season crops such as watermelon and other horticultural crops to reduce water evaporation, decrease soil compaction and fertilizer leaching, modify soil temperature, control weeds andincrease yield. In general, black plastic mulch is recommended in Louisiana for spring and fall vegetable production while white plastic mulchis recommended for the summer growing season.

LSU AgCenter and Mississippi State University researchers are starting a project to measure how well nonindustrial private forest landowners understand certification programs.

Cotton is a perennial plant capable of recovering from many stresses during Louisiana’s long growing season, including insect damage. However, as plants near maturity, their capacity to recover from stresses is reduced.

School gardens are used as outdoor classrooms around the United States to supplement the curriculum. Educators have reported that school gardens can be used to teach across the curriculum and that concepts and skills from virtually every subject can be learned through a school garden.

Louisiana’s agriculture and seafood industries will have a new marketing tool in early 2010 when MarketMaker, a national Internet-driven service, is inauguratedin the state.

The LSU AgCenter has received grants totaling nearly $1.26 million during the past few months.

The Clearfield system, which involves herbicide-resistant rice, offers for the first time the ability to selectively eliminate the weed red rice from a production rice field with the use of an herbicide. But the system must be used following strict guidelines. Otherwise, its future as a way to prevent red rice is limited.

It is hypothesized that the level of environmental degradation will increase as per capita income increases up to a certain level. Then, the level of degradation will decrease with further growth in income, which would be beneficial to the environment. This relationship between environmental quality and per capita income would thus assume an inverted U shape.

The continuing transformation of U.S. agriculture profoundly affects the economies in rural America. The LSU AgCenter is attempting to bring relief to one of the most impoverished parts of the country through an innovative, economic and rural development educational program.

The lack of basic leadership skills and economic development knowledge is often identified by focus groups and advisory councils as a problem in rural areas.

The U.S. rural economy is often described as declining, even devastated, and at best as in a state of flux. To be sure, many rural communities in the United States are struggling to exist. Today’s economy is far less local than it ever has been. Because of technology, we can buy and sell almost anything globally in the time it takes to click “send” on our computer screens.

Experiences during the teenage years play a large role in determining whether teenagers go on to become productive and engaged citizens as adults.

Rural America is turning to nature to revitalize its communities.Ironically, farming communities with enhanced natural amenities may boost business opportunities.

The two-year “Be Child Care Aware!” educational campaign, launched in the fall of 2003, reached at least 205,000 people with information on quality child care.

It’s a fact. Most tots and toddlers spend the majority of their waking moments in child-care programs.

The LSU AgCenter’s Community Leadership and Economic Development Program received the 2005 training achievements award from the International Economic Development Council during the council’s annual meeting in Chicago in September.

The effect of early experiences on a child’s later success is well-documented by social scientists. Because young children are increasingly spending more of their early years in a variety of settings, it is critical that they receive high-quality care and education during these formative years.

In a recent report to the LSU System, an auditor of LSU’s technology transfer activities referred to the LSU AgCenter’s Office of Intellectual Property as the “crown jewel” of the system because of its productivity.

“Don’t give up” was the message from North Carolina's 4-H’ers to those in Louisiana who were affected by the recent hurricanes.

For decades, globalization and advances in information and communication technology have been creating two different kinds of jobs in the United States. Primary sector jobs are high-skilled, high-paying, stable and offer opportunities for advancement. Secondary sector jobs are low-skilled, low-paying, unsecured, monotonous and offer few opportunities to advance.

The National Science Foundation has awarded a $336,898 grant to Robert Laird through LSU A&M. Laird has a joint appointment with the LSU AgCenter, and the grant will allow him to continue his research on parenting teenagers.

The primary mission of the LSU AgCenter is to enhance the quality of life for people through research and education. This issue of Louisiana Agriculture concentrates on the AgCenter’s research and education efforts to enhance the social and economic development of families and their communities.

Rural development makes America a better place in which to live and work. Rural development emphasizes the well-being of people rather than economic growth itself. Development increases real per capita incomes and employment and improves housing, fire and police protection, schools, libraries and other government services. These amenities in rural communities are directly influenced by farmers. Also, the well-being of farmers is affected by communities.

Losing the roof on your home to high winds can be an expensive proposition. High winds can literally lift the roof off a house. Then you not only have to take care of the damage to the roof itself but also the damage to the inside of the house.

Financial security plays a major role in a person’s overall feeling of well-being and satisfaction. The Jump$tart Coalition for Personal Financial Literacy is a partnership comprising representatives from business, industry, government, education and nonprofit groups that seeks to improve the personal financial literacy of young adults.

Factory-made wall, ceiling and roof panels are among the four building systems of the LSU AgCenter’s state-of-the-art demonstration house that can withstand Louisiana’s climate and harshest elements, including hurricane winds.

With recent hurricanes battering the state, Louisianians are increasingly concerned about how to protect themselves from strong winds. An innovation at the LaHouse project is called a "safe room."

Sustainability in housing (meeting current needs without jeopardizing future generations) is an emerging necessity. Natural disasters such as hurricanes Katrina and Rita in 2005 cause billions of dollars in damages to homes.

The Formosan termite is a devastating pest that consumes wooden structures and woody plants and causes hundreds of millions of dollars of damage each year. The LSU AgCenter is making progress slowing its spread in the New Orleans' French Quarter, despite the devastation of Hurricane Katrina.

Established as the Fruit and Truck Experiment Station in January 1922, the LSU AgCenter’s Hammond Research Station has served the needs of the strawberry and vegetable industries in Southeast Louisiana for more than 80 years.

Those of us who have the privilege of being a professional horticulturist enjoy the reward of knowing that we directly touch the lives of every single citizen in Louisiana every day. The science and art of horticulture remains a dynamic influence on our lives.

The LSU AgCenter's mission is to serve Louisiana. And the employees did. In some cases, they were there to help others after hurricanes Katrina and Rita at great personal sacrifice to themselves. Read about the LSU AgCenter's response.

Nearly all of the rice grown in Louisiana was developed at the LSU AgCenter’s Rice Research Station in Crowley.

In 20 years, the LSU AgCenter’s small-grains breeding program has grown from nothing to being the source of the most widely planted wheat variety in Louisiana.

What to do with decommissioned, preservative-treated wood has become a burning issue. Well, not burning, actually. That’s one of the methods that can’t be used any longer, according to Todd Shupe, a forest products researcher in the LSU AgCenter’s School of Renewable Natural Resources. Shupe has been looking for answers for what to do with the products no longer serviceable.

Red rice, a noxious weed in rice, costs rice producers millions of dollars each year. Red rice is physiologically similar to rice. Consequently, rice andred rice are susceptible to the same herbicides, so controlling red rice with herbicides in rice fields is difficult.

Ricestar (fenoxyprop), a relatively new selective herbicide, is used for postemergence control of grasses in rice. It provides good to excellent control of major grasses such as barnyardgrass, broadleaf signalgrass and sprangletop.

Rural economic development addresses factors to increase the quality of rural life including the availability of infrastructure. The research and extension activities of the LSU AgCenter have adapted over time to meet the changing structure of our rural economies to promote their growth and well-being.

The LSU AgCenter has added strength to its quest to help organize an economic development strategy in the Northeast Louisiana. The added force is James Barnes, new director of the Delta Rural Development Center in Oak Grove.

Bedding plants are widely used in landscaping or in containers. Two-thirds of the value of U.S. floriculture production in 2002 consisted of bedding plants. Salvias have been one of the most common bedding plants used in landscaping and as a pot plant.

Research has found a consistent sorghum yield response to row widths narrower than 40 inches, particularly on alluvial soils. On Macon Ridge soils, narrow rows tend to yield better than wider rows in years with adequate rainfall, while wider rows are superior to narrow row widths in rain-deficient years.

Two years into her job has resident coordinator of the Hammond Research Station, Regina Bracy still considers it challenging and fun.

The green industry (nursery, landscape, greenhouse, sod and allied industries) is growing in Louisiana and nationally. This growth is fueled by changes in consumer incomes and demographics. Consumers continue to allocate a portion of their increased incomes to home improvements, including their lawns and gardens.

The LSU AgCenter offers help to nursery owners in their continual battle against pests, especially insect pests.

The LSU AgCenter has long had an All-America Rose Selections Display Garden, first at the Hill Farm location on the LSU campus and now at Burden Center in Baton Rouge. Many rose varieties have been evaluated over the years.

Five years ago, the LSU AgCenter decided to dedicate a 20-acre site at Burden Center in Baton Rouge as a home for ornamental and turfgrass research and demonstration projects. And it has flourished ever since.

The Mexican rice borer has been the major economic pest in Texas sugarcane since it became established in 1980, quickly surpassing that same year the sugarcane borer in economic importance. Even though the insect has not yet been found in Louisiana, scientists from both states and from the U.S. Department of Agriculture are working together to conduct research on the areawide population dynamics of the Mexican rice borer and to develop cultural and production practices to reduce its spread.

Current technologies for the prevention and treatment of cancer are far from being effective at safe, non-toxic doses. Standard chemotherapeutic drugs are all designed to be toxic, harming cancerous and healthy tissues to varying degrees. Targeted therapies such as angiogenic inhibitors directed toward specific receptors or growth-factor pathways offer hope in managing cancer.

Southern yellow pine (SYP) has for many years provided the homebuilding industry with abundant, cost-competitive wood products. Recent research indicates that softwood lumber, including SYP, continues to lose market share in the U.S. residential construction industry to substitute products such as concrete, steel and plastic and that builders remain concerned about softwood lumber quality and price.

Several physical, chemical and biological factors can influence corn seedling development and reduce maximum yield potential. Early-season seedling defoliation can make replant decisions difficult. Producers typically underestimate the resilience of corn plants after they undergo early-season injury.

Most greenhouse tomato operations in the southern United States are small. These growers have to hold down production costs to compete well in a market dominated by more efficient, larger operations. One way they do this is to reuse the root medium (perlite) for growing the greenhouse tomato plants.

Research has found a consistent sorghum yield response to row widths narrower than 40 inches, particularly on alluvial soils. On Macon Ridge soils, narrow rows tend to yield better than wider rows in years with adequate rainfall, while wider rows are superior to narrow row widths in rain-deficient years.

Annual bluegrass and henbit are the most common and frequently targeted weeds in Louisiana wheat. Ryegrass is the most challenging weed to manage in Louisiana wheat and is increasing in abundance.

Table on the occurrence of Hessian fly and grain yield of 26 common what varieties in Louisiana. Content relates to Lousiana Agriculture Winter 2011 issue, article on page 15

The art and science of plant breeding has evolved much since it was first practiced during the early stages of crop domestication. This study compares breeders' estimates with observed yields.

Hessian fly is one of the most destructive pests of wheat worldwide. This pest was first detected in the United States on Long Island, N.Y., in 1778, and is thought to have been introduced to this country by the Hessian soldiers during the Revolutionary War.

It’s tough to become a Super Plant. But once a plant gets that designation, it will be promoted as an ideal plant for Louisiana.

Disposal of solid waste is a growing concern to municipal officials and corporate managers, and in some sections of thecountry, critical. As the population grows and industrial productionincreases, so does waste. At the same time, disposal costs have increased, often dramatically, because of increased regulationand centralization of waste disposal sites.

Resistance monitoring provides a useful tool for detecting changes in the insecticide susceptibility of field populations of insect species from year to year.

The abundance of stink bugs has increased in Mid-South and Southeastern cotton-producing states in the last six years. Stink bugs have become more common cotton pests because of a number of changes in Louisiana’s agricultural environment that have made crop and noncrop hosts available year-round.

Legislation designed to protect specific species dates back to early history in the United States. However, the Endangered Species Act of 1966 was the first piece of legislation specifically addressing species with a threatened or endangered status. In 1973, the Endangered Species Act (ESA) was modified to include plants as well as animals.

Transgenic technology has had a dramatic effect on cotton production. In 2002, more than 70 percent of Louisiana cotton acreage was planted to transgenic varieties. Cotton varieties resistant to herbicides glyphosate (Roundup Ready), bromoxynil (BXN) and glufosinate (Liberty Link) have been developed.

Many fishery species rely on estuaries as critical habitat during early life stages, including redfish, menhaden, shrimp, blue crab, croaker and flounder. Because of the economic importance of many of these fishery species, the success of many coastal restoration projects is partially determined by the habitat provided for them.

A decline in loblolly pine, first reported in Bogalusa, La., in 1966, helped trigger a long-term study at the LSU AgCenter. At first, it was suspected that it was the same disease as littleleaf disease of shortleaf pine, which was attributed to site factors and Phyphthora cinnamomi, a water mold.

The tarnished plant bug has always caused problems in cotton, but in recent years the problems have escalated. Data from 1990 to 1995, before the advent of transgenic Bt cotton, put the cost per acre to control the tarnished plant bug at $3.19 compared to $12.02 from 1996 to 2002, after Bt cotton was introduced.

Louisiana’s coastal waters, lakes, rivers and bayous are the lifeblood of the state. They have provided economic survival and year-round recreation, earning the state the well-deserved title of “Sportsman’s Paradise.”

Much of the land where cotton is grown in Louisiana has been used for cotton production for decades. This has left the soil deficient in both nutrients and organic matter. Some of these deficiencies could potentially be corrected by supplementing these soils with organic waste from Louisiana’s poultry industry. This is the state’s largest animal industry generating tons of organic waste that must be disposed of in an environmentally friendly manner

The rich, fertile soils of the Red River valley of northwestern Louisiana have supported cotton production for decades. Unfortunately, as in most agricultural soils, continuous cultivation has resulted in a steady decline in native soil fertility, especially organic matter.

In Louisiana, most row crops are produced on “stale” seedbeds, which means the fields are prepared in the fall,allowing vegetation to cover the field over the winter and help prevent soil erosion.

Entomologists for many years have dealt with insect resistance to insecticides. For weed scientists, however, weed resistance to herbicides is relatively new.

Solid wood forest products as opposed to pulp and paper products can be characterized broadly as primary or secondary. This classification is not always clear, but most industry observers agree that primary products are those produced directly from raw timber input. Examples include chips, lumber, veneer, plywood and their byproducts.

The LSU AgCenter is operating a program in Ukraine that is a model for how to run a successful educational effort in a country formerly part of the Soviet bloc. The program, “Improving Income of Private Ukrainian Agricultural Producers,” targets farmers with fewer than 250 hectares and household plot owners (HPOs).

In recent years, many large food and beverage companies have adopted team approaches to new product development. The approach typically involves both a marketing department and a research and development department generating product ideas, concepts and ultimately prototypes, which are subsequently tested in selected target markets.

Crop nutrient demand and nutrient supply from broiler production by parish in 2008

The growing demand for food and fuel in the world has spurred widespread concern about the sustainability of agriculture’s intensive use of energy and nutrients. An easy and cost-effective method to improve nutrient balance in animal husbandry is to reduc inputs.

For more than 100 years cotton has been the most important crop grown in northeast Louisiana. At one time cotton was grown all across the state, but over the years it has become concentrated in the northeast part because of more favorable environmental conditions and because other crops are preferred in south Louisiana.

The aquaculture industry is looking increasingly to genetic improvement for gains in production. But improving the genetics of aquatic species can take a long time. With catfish, for instance, a male typically spawns with only one female each season. Even if genetically superior males and females could be identified, the process of developing breeding stock and improved lines could take a decade or more.

Strawberries are one of the most popular fruit crops grown in the world. Per capita consumption of fresh strawberries in the United States has increased in the past 10 years and is predicted to continue to rise in the foreseeable future. Most U.S. commercial production of strawberries is in California where the arid climate and low disease pressure make ideal growing conditions.

The bacterial genus Brucella includes six recognized species. They are characterized by the animals that they preferentially infect.
